Hello, here I'd like to introduce you to a thin back exercise, which is to eliminate back fat and exercise back muscles and scapula muscles through prone and upturned movements, so as to eliminate shoulder and back fat and make muscles firm. Its effect will certainly satisfy you. Try it if you don't believe me: Exercise location: You can exercise on the sofa or wooden floor in the office. Time: half an hour after lunch. Don't exercise on an empty stomach, it's harmful to your health. Preparation: prone, shoulders relaxed, hands crossed on hips. Specific steps: first close your chin and slowly lift your upper body about 35 degrees. Then slowly lower the upper body and return to the preparatory action. Practice method Upper body lifting action * * * 20 times. You can rest for 30 seconds every time you do it. Don't do it too fast and don't do it too slowly. One thing you should remember: the upward angle should not be too large, and it should never exceed 35 degrees, because it is easy to hurt the spine. As long as you keep doing it for half a month, you will lose a lot of fat on your back. Of course, when you lose your back, your spirit will be much better.
